TRANSMISSION-GEARING.

' Specification of Letters Patent.

Application filed July 8, 19 Serial No. 708,155.

To all whom it may concern:

Be it known that I, WALTER D. ARNS:

BURGER, a citizen of the United States, residingat Patch Grove, in the county.of Grant, State of Wisconsin, have invented certain new and useful Improvements in Transmission-Gearing; and I do declare the.

following to be a full, clear, and exact de scription of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to the characters of reference marked thereon, which form a part of this applica tion.

This invention relates to improvements in transmission gearing for motor vehicles, the object of the invention being to produce a direct clutch mechanism for each change gear whereby there will be no need of any intermediate clutch between the motor and the transmission gearing nor any necessity of throwing said clutch out and in every time a change of speed is made, but the aim of my invention is to produce a means whereby by merely shifting the operating lever the different speeds may be had.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusalv of the following specification and claims.

On the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a top plan view of my transmission gearing showing the gears well spaced apart in order to equally demonstrate the different mechanisms. Fig. 2 is a fragmentary view showing a rod shifting mechanism.

The numeral 1 designates the usual gear casing which may be provided with suitable bearings and so forth for the various shafts to be hereinafter described, the samebeing of any ordinary type therefore no specific description of the same will be hereinafter iven.

g The numeral 2 designates the usual driving shaft from the engine which drives a gear 3 intermeshing with a larger gear l keyed onto a shaft 5; The numeral 6 designates a gear loosely to the shaft 8 thus mounted 'onthe shaft 5 with a gear 7keyed to a shaft 8.

The numeral 9 designates a gear loosely mounted on the shaft 5 and intermeshing with a gear '10 keyed to the shaftv8.

The numeral lldesignates a gear loosely 'mounted on the shaft 5 and engaging a gear 'Pate'ntedNov. 25,1913.

and inter-meshing.

12 mounted on a stub 13, which gear-12 intermeshes with a gear shaft 8. v I

The numeral 15 designatesa crank shaft, the movement of which is'controlled by an operating lever 16 provided with a shaft 16 carrying a quadrant gear 16" adapted to engage a quadrantgear 15 upon the said shaft 15.. The member 16 through an H-shaped guide 17 inwhich the points as described on the drawings, tow'it: H, I, Sand R will be used to designate the different points in said guide 17 for the movement of thelever. 16, the opera tion of which lever will change the speed of theshaft 8 which is the driven shaft as will appear.

Connected with the shaft 15 is a lever 18 adapted to drive a collar 19 connected l4 keyed to the p by links 20 with frictional bands 21 adapted to project into and engage the inner surface of the gear 6. To attain this result the lever 16 is moved to the point indicated as I and causes the gear 16 to engage the gear 5* and move the shaft 15, which will operate the lever 18 with the above result. The gears 34-6-7 are so proportioned that this speed will be the intermediate speed of the vehicle. Similarly by throwing the lever 16 to the point indicated as H this will is movable cause a lever 22 which is connected with the I crank shaft 15 to drive a collar 23 to cause links 24 to engage frictional bands 25 against the inner circumference of a ring 26 indicated as a part of the gear 3 which will give the direct drive from the shaft 2 giving high speed to the vehicle. Similarly by moving the lever 16 to the point S, this engages the gear 16 with a gear 27 mounted on a sleeve 27, which action turns the said sleeve 27 and causes it to operate a rod 28 to turn a lever 29. This moves the sleeveSO to cause a collar 31 to operate links 32 to engage frictional bands 33 with the interior surface of a ring 34 secured to the gear 9, which by reason of the proportion of the gears gives a slow speed to the shaft 8. Also by pulling the lever 16 to the point marked R this will cause the inembers 27, 28 and 29 tooperate to drive a sleeve-35 :te move a collar :36 to drive links 37 to cause friction bands 28 to engagethe inner surface Of'lt1le gea=1' 11: Which driving through the gears 12 and 1.4:.

drives the shaft 8 in a reverse direction from its forward direction. 7 All of the collars are of course keyed to their respectiveshafts.

While I have shown herein one particular Lfer mfof clutclrand one particul ar form of operating means therefor still in practice iit i'ni'gh't befound desirable to use a differ- :Zent-form from-that shown in the drawings, Ythe main= object-cf the invention being, of

:xce'urse, the idea ;of having an independent varied movement of the driven shaft'8.

i From the foregoing description it will 3 be readily seen that I have produced such hile -this specification sets forth in de-v edevicefas siibstantially fulfils the objects of the invention as set-forth "herein;

tail the present I and :preferred construction f the device, still'in' practice such deviaions from such detailmay-be resorted to as de not form a departi'i're from "the spirit of the invention. I

Having thus described my invention what I claim as new and useful and desire to securejby-Letters Patent is:

A device of the character described comprising a driving shaft and a driven shaft, a third shaft, a gear on said driving shaft, agear on said third shaft intermeshing with said gear on said driving shaft, a plurality of gears on said driven shaft and a plurality of gears on said third shaft engaging said plurality of gears on said driven shaft, an independent clutch adapted to engage the gear on said driving shaft'and each of the plurality of germs on said third shaft, means for operating said clutch members, such nieans comprising a turnable rod, =links conneeting said rod with certain ones of said connecting said sleeve with .the remaining clutch members, a gear on said rod and said sleeve, and'=ashift-in'g leverprovided with a *gear adapted to 'engageieach of the gearsio'n said. rod and said sleeve, as described.

In testimony whereof I 'afiix my signature in presence of two Witnesses.
